Bernie Sanders, Zohran Mamdani team up to 'fight oligarchy' in NYC

"It is an honor to welcome Senator Sanders to New York City as we fight against the corporate greed, billionaires, and corrupt politicians responsible for the affordability crisis," Mamdani said in a statement ahead of the "Fighting Oligarchy" event in Brooklyn. 

Trump has dubbed Mamdani a "100% Communist Lunatic." 

Ahead of the town hall in Brooklyn, the two progressive leaders plan to march alongside union members in Manhattan's Labor Day parade on Saturday morning. 

"No, billionaires should not be able to get away with not paying their fair share of taxes while working people are being, in many cases, overtaxed," Sanders said, urging Americans to unite against Trump and deliver for more than just the top 1%. 

Mamdani called Sanders "Brooklyn through and through" and said it was an honor to meet "one of my heroes," while Sanders said he is "deeply impressed by the grassroots campaign he is running."

Sanders, a two-time Democratic presidential nominee runner-up, was an early endorser of Mamdani's primary campaign, alongside Ocasio-Cortez. Their endorsements helped Mamdani consolidate progressive support in the 11-candidate field during the final weeks of the primary campaign.

While Sanders' "Fighting Oligarchy" tour seemed for a time a glimmer of hope for a fractured party, Mamdani's surprising primary win this summer seems to have reignited that Democratic base in a new, albeit more progressive, direction. 

"At a time of massive and growing income and wealth inequality, we are building a strong grassroots movement to take on the billionaire class and corporate greed," Sanders said in a statement ahead of the Brooklyn town hall. 

Sanders said the "oligarchs" - or wealthy business leaders with political influence - will "undermine democracy" and won't hesitate to "buy elections." 

"But candidates who stand boldly with the working class can - and will - beat them. When we stand together we can defeat authoritarianism and create an economy that works for all our people, not just the privileged few," the Vermont senator and former presidential candidate said. 

Sanders' campaign has touted turning out more than 300,000 people across 34 rallies in 20 states since kicking off his "Fighting Oligarchy" tour this year. 

Fox News Digital reached out to Republican nominee Curtis Sliwa, Cuomo and Adams for comment regarding Mamdani's event with Sanders but did not immediately receive responses.
